Embodiment
Below in conjunction with accompanying drawing image die set and image module are further detailed.
As Figure 1-3, the image module 10 of one embodiment, comprise image die set 100, flexible PCB 200, capacitance component 300, sensitive chip 400, support 500, IR(Infrared Spectroscopy, infrared spectrum) optical filter 600 and IC(Integrated Circuit, integrated circuit) chip 700.
Image die set 100 comprises voice coil motor 110, camera lens 120 and diaphragm 130.
When camera lens 120 protrudes first surface 111; second through hole 132 is used for the part that ccontaining camera lens 120 protrudes from first surface 111; thereby make camera lens 120 not protrude from diaphragm 120 away from a side of first surface 111; also namely make camera lens 120 a little less than the side of diaphragm 120 away from first surface 111; or make camera lens 120 and the side of diaphragm 120 away from first surface 111 maintain an equal level, and then reach the purpose of len 120.
The thickness of diaphragm 130 determines the hole depth of second through hole 132, and the hole depth of second through hole 132 need protrude from the height of the part of first surface 111 more than or equal to camera lens 120.Dissimilar image module 10 its camera lenses 120 protrude from the height difference of the part of first surface 111, and usually the height that protrudes from the part of first surface 111 according to camera lens 120 selects to have the diaphragm 130 of suitable thickness.In the present embodiment, the thickness of diaphragm 130 is preferably 0.1～0.4 millimeter.
The material of diaphragm 130 is extremely important for the thickness of diaphragm 130, if the material hardness of diaphragm 130 is bigger, has strong external force resistance ability, even the thickness of diaphragm 130 is very little so, also can make diaphragm 130 have the performance of better protect camera lens 120.Therefore, in the present embodiment, diaphragm 130 is preferably hardness greater than the 55HS(shore hardness) the silica gel sheet.The relatively good control of silica gel thickness, and material cost is lower, and processing obtains the silica gel sheet of all thickness easily.Be appreciated that in other embodiments diaphragm 130 also can and have the material of better transmittance for the big hardness of having of other, as, optical grade polyethylene terephthalate plate.
In the present embodiment, second through hole 132 is identical near size and the shape of an end of first surface 111 with first through hole, and second through hole 132 is circular.Thereby make diaphragm 130 and first surface 111 have relatively large contact area, and then be conducive to diaphragm 130 firm being fixed on the first surface 111.
Be appreciated that in other embodiments the shape of second through hole 132 can be identical near the shape of an end of first surface 111 with first through hole, and the size of second through hole 132 can be greater than the size of first through hole near an end of first surface 111.The shape of second through hole 132 also can be inequality near the shape of an end of first surface 111 with first through hole, and the shape of second through hole 132 also can be regular polygon etc.
In the present embodiment, shell 112 is cuboid, and its first surface 111 is square with second surface 113.Be appreciated that in other embodiments the first surface 111 of shell 112 also can be other shapes, as circular, oval or other regular polygons etc.
In the present embodiment, the shape of diaphragm 130 is identical with the shape of first surface 111, and diaphragm 130 covers first surface 111.Thereby make the diaphragm 130 that is fixed on the first surface 111 have bigger contact area with first surface 111, and then be conducive to diaphragm 130 firm being fixed on the first surface 111.Wherein, diaphragm 130 covering first surfaces 111 also are that the outer peripheral edge portion of diaphragm 130 overlaps with the outer peripheral edge portion of first surface 111, or the outer peripheral edge portion of diaphragm 130 protrudes from first surface 111.
Be appreciated that, in other embodiments, the shape of diaphragm 130 is identical with the shape of first surface 111, but the area of the side that diaphragm 130 and first surface 111 are close is less than the area (not covered by diaphragm 130 on the part first surface 111) of first surface 111, be conducive to reduce the consumption of diaphragm 130, be beneficial to and reduce layer originally, and on the first surface 111 not fixedly the part of diaphragm 130 have relatively low height, be more conducive to image module 10 and other correlated parts and be used to reach peak use rate to the space.Certainly, the shape of the shape of diaphragm 130 and first surface 111 also can be inequality.
In present embodiment, the mode that diaphragm 130 adopts sticker to close is fixed on the first surface 111.Wherein, the paste attachment that adopts of the sticker mode of closing is list or double faced adhesive tape.Be appreciated that in other embodiments, also can be according to the material of diaphragm 130, adopt other more reasonable manner diaphragm 130 is fixed on the first surface 111, as, modes such as engaging, Electrostatic Absorption, glue bonding.
In the present embodiment, capacitance component 300 and sensitive chip 400 are located on the flexible PCB 200, and sensitive chip 400 is electrically connected with flexible PCB 200 by gold thread 410, pass through flexible PCB 200 again and are electrically connected with capacitance component 300.
In the present embodiment, also be provided with IC chip 700 on the end of flexible PCB 200 away from support 500, IC chip 700 is electrically connected with flexible PCB 200.
In the present embodiment, first openend 510 of support 500 adopts the mode of welding to be fixed on the flexible PCB 200, and the mode that the second surface 113 of shell 112 adopts sticker to close is fixed on second openend 520 of support 500.
On the first surface 111 of the voice coil motor 110 of above-mentioned image module 10 diaphragm 130 is arranged fixedly, and diaphragm 130 offers second through hole 132 that runs through diaphragm 130 over against camera lens 120 places.When camera lens 120 protrudes first surface 111, second through hole 132 is used for the part that ccontaining camera lens 120 protrudes from first surface 111, thereby make camera lens 120 not protrude from diaphragm 130 away from a side of first surface 111, can effectively avoid the camera lens 120 of image module 10 in links such as test, transportation, assembling, to be damaged or to scratch.Therefore, the effective len 120 of above-mentioned image module 10.And when being assembled in above-mentioned image module 10 in the mobile phone, the situation that camera lens 120 contacts with correlated parts in the mobile phone can not appear, thus can not damage the correlated parts in the mobile phone, do not influence the effect of taking pictures simultaneously yet.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
